Existence of solutions for an Oldroyd model of viscoelastic fluids. (English) Zbl 1162.76004
Summary: We investigate the unilateral problem for an Oldroyd model of viscoelastic fluid. Using the penalty method, Faedo-Galerkin approximation, and basic result from the theory of monotone operators, we establish the existence of weak solutions.
